In the games

In Diamond and Pearl

The Hearthome Gym is a giant, five-story building constructed of gray stone blocks, and is illuminated by eerie gray-blue torches. On every floor, there is a simple mathematical puzzle and three doors corresponding with the answers. Picking the correct door leads to the next elevator up, while picking the wrong door leads to a dead end and a Trainer to fight. The Pokétch has a Calculator App, which can be used to find the answers with minimal effort. The Gym Leader waits in the final room on the fifth floor, which has stained glass windows and resembles a cathedral.

In Platinum

In Pokémon Platinum, Hearthome Gym has become much like Dewford Gym from Generation III; it is dark, and the only light source is limited. The player must navigate their way around the Gym using a flashlight to locate a blue tile on the floor, which corresponds to the correct door. Entering the wrong door will result in the player returning to the lobby, and the blue tile is reset each time the player enters the Gym. Duskull lamps are used as visible walls, to guide the player around. There are other Trainers with flashlights the player must battle, in order to make their way to Fantina.

She is the third Gym Leader in this game, able to be battled on the first visit to Hearthome. Although Fantina uses similar Pokémon, at different levels, she no longer has Drifblim, her original signature Pokémon.
